In this report, the authors describe an extended corresponding states model for viscosity and thermal conductivity of mixtures implemented in Version 8 of the NIST computer program REFPROP. The model is a modification of a one-fluid, extended corresponding states (ECS) model for thermal conductivity and viscosity originally developed by Ely and Hanley The authors apply the model to selected mixtures representative of the fluids available in the NIST 23 database REFPROP (v8), such as refrigerants and natural gas constituent fluids, and present comparisons with experimental data. Comparisons...

The Standard Platinum Resistance Thermometer (SPRT) is defined by the International Temperature Scale of 1990 (ITS-90) as the interpolating instrument for temperatures between 13.8033 K and 1234.93 K. This SRM concerns the calibration characteristics of a group of 20 capsule-type SPRTs within the range of temperatures between 13.8033 K and 429.7485 K. The platinum wire used for the construction of the resistor elements of this SRM was derived from platinum bar stock with a chemical purity of 99.999 % by weight. Each of the 20 units has been evaluated, certified, and calibrated according to...

This document details the proceedings of the Dynamic Measurement and Control for Autonomous Manufacturing Workshops held October 10 - 11, 2007 at Loyola College of Maryland.

Bluetooth is an open standard for short-range radio frequency communication. Bluetooth technology is used primarily to establish wireless personal area networks (WPANs), and it has been integrated into many types of business and consumer devices. This publication provides information on the security capabilities of Bluetooth technologies and gives recommendations to organizations employing Bluetooth technologies on securing them effectively. The Bluetooth versions within the scope of this publication are versions 1.1, 1.2, 2.0 + Enhanced Data Rate (EDR), 2.1 + EDR, 3.0 + High Speed (HS), and...

This study developed a time domain, database-assisted design (DAD) procedure that uses a multiple points-in-time (MPIT) approach, and illustrated the procedure by an application to a 60-story reinforced concrete structure.

BridgeLCC 2.0 is user-friendly software developed by the National Institute of Standards and Technology to help bridge designers determine the cost effectiveness of alternative bridge designs, construction and repair strategies, and construction materials. The software uses a life-cycle costing methodology based on the ASTM standard practice for life-cycle costing and a cost classification scheme developed by NIST. This user manual describes the functions and settings in BridgeLCC and includes example analyses that illustrate its use.

This report defines version 2.0 of the Open Checklist Interactive Language (OCIL). The intent of OCIL is to provide a standardized basis for expressing questionnaires and related information, such as answers to questions and final questionnaire results, so that the questionnaires can use a standardized, machinereadable approach to interacting with humans and using information stored during previous data collection efforts. OCIL documents are Extensible Markup Language (XML) based. This report defines and explains the requirements that IT products and OCIL documents asserting conformance with...

The purpose of this report is to provide technical guidance regarding the design and development of EHR systems, which will help to prevent the creation or exacerbation of healthcare disparities with the national adoption and utilization of EHR systems.

This report was conducted by the Applied Economics Office in the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). The report is designed to document the assumptions used in creating the whole building energy simulations used for new commercial building prototypes. The intended audience is the building research community, particularly those concerned with energy efficiency in commercial building designs.

This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, the Data Encryption Algorithm (DEA). When implemented in an SP 800-38-series-compliant mode of operation and in a FIPS 140-2-compliant cryptographic module, TDEA may be used by Federal organizations to protect sensitive unclassified data. Protection of data during transmission or while in storage may be necessary to maintain the confidentiality and integrity of the information represented by the data. This Recommendation defines the mathematical steps required to...
